Yes. ClassLoader.getURLs() is used. Few other complonents are added: - the classpath option ( init param for the servlet, or part of the Option object used to construct jasper ). - system property: java.class.path - context property: org.apache.catalina.jsp_classpath If you need an additional hook - just send a patch to jasper :-) BTW, ant is used only in jasper2, but the mechanism is similar > Boot libraries are not copied to the local machine first so have URLs > based on HOME_URL.

Just set them in the Context or system property ( after you convert them to file: - javac or jikes can't handle anything else ). That's the hook most containers use ( or should use ) to pass additional classpath to jasper.
